Waxy Flexibility
Waxy flexibility is a psychomotor symptom of catatonia as associated with schizophrenia, bipolar disorder, or other mental disorders which leads to a decreased response to stimuli and a tendency to remain in an immobile posture. Attempts to reposition the patient are met by "slight, even resistance", and after being repositioned, the patient will typically remain in the new position. Waxy flexibility rarely occurs in cases of delirium. The presence of waxy flexibility along with at least two other catatonic symptoms such as stupor or negativism are enough to warrant a diagnosis of catatonia. If one were to move the arm of someone with waxy flexibility, the patient would keep that arm where it had been positioned until moved again, as if positioning malleable wax. Further alteration of an individual's posture is similar to bending a candle. Although waxy flexibility has historically been linked to schizophrenia, there are also other disorders which it may be associated with, such ...

Psychiatry
Psychiatry is the medical specialty devoted to the diagnosis, prevention, and treatment of mental disorders. These include various maladaptations related to mood, behaviour, cognition, and perceptions. See glossary of psychiatry. Initial psychiatric assessment of a person typically begins with a case history and mental status examination. Physical examinations and psychological tests may be conducted. On occasion, neuroimaging or other neurophysiological techniques are used. Mental disorders are often diagnosed in accordance with clinical concepts listed in diagnostic manuals such as the ''International Classification of Diseases'' (ICD), edited and used by the World Health Organization (WHO) and the widely used '' Diagnostic and Statistical Manual of Mental Disorders'' (DSM), published by the American Psychiatric Association (APA). The fifth edition of the DSM (DSM-5) was published in May 2013 which re-organized the larger categories of various diseases and expanded upon the p ...

Catatonia
Catatonia is a complex neuropsychiatric behavioral syndrome that is characterized by abnormal movements, immobility, abnormal behaviors, and withdrawal. The onset of catatonia can be acute or subtle and symptoms can wax, wane, or change during episodes. There are several subtypes of catatonia: akinetic catatonia, excited catatonia, malignant catatonia, delirious mania, and self-injurious behaviors in autism. Although catatonia has historically been related to schizophrenia (catatonic schizophrenia), catatonia is most often seen in mood disorders. It is now known that catatonic symptoms are nonspecific and may be observed in other mental, neurological, and medical conditions. Catatonia is not a stand-alone diagnosis (although some experts disagree), and the term is used to describe a feature of the underlying disorder. Recognizing and treating catatonia is very important as failure to do so can lead to poor outcomes and can be potentially fatal. Treatment with benzodiazepines o ...

Stupor
Stupor is the lack of critical mental function and a level of consciousness, in which an affected person is almost entirely unresponsive and responds only to intense stimuli such as pain. The word derives from the Latin '' stupor'' ("numbness, insensibility"). Signs and symptoms Stupor is characterised by impaired reaction to external stimuli. Those in a stuporous state are rigid, mute and only appear to be conscious, as the eyes are open and follow surrounding objects. If not stimulated externally, a patient with stupor will appear to be in a sleepy state most of the time. In some extreme cases of severe depressive disorders the patient can become motionless, lose their appetite and become mute. Short periods of restricted responsivity can be achieved by intense stimulation (e.g. pain, bright light, loud noise, shock). Causes Stupor is associated with infectious diseases, complicated toxic states (e.g. heavy metals), severe hypothermia, mental illnesses (e.g. schizophrenia, majo ...

Electroconvulsive Therapy
Electroconvulsive therapy (ECT) is a psychiatry, psychiatric treatment where a generalized seizure (without muscular convulsions) is electrically induced to manage refractory mental disorders.Rudorfer, MV, Henry, ME, Sackeim, HA (2003)"Electroconvulsive therapy". In A Tasman, J Kay, JA Lieberman (eds) ''Psychiatry, Second Edition''. Chichester: John Wiley & Sons Ltd, 1865–1901. Typically, 70 to 120 volts are applied externally to the patient's head, resulting in approximately 800 amperes, milliamperes of direct current passing between the electrodes, for a duration of 100 milliseconds to 6 seconds, either from temple to temple (bilateral ECT) or from front to back of one side of the head (unilateral ECT). However, only about 1% of the electrical current crosses the bony skull into the brain because skull Electrical impedance, impedance is about 100 times higher than skin Electrical impedance, impedance. The ECT procedure was first conducted in 1938 by Italian psychiatrist Ugo C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Catalepsy
Catalepsy (from Ancient Greek , , "seizing, grasping") is a nervous condition characterized by muscular rigidity and fixity of posture regardless of external stimuli, as well as decreased sensitivity to pain. Signs and symptoms Symptoms include a rigid body, rigid limbs, limbs staying in same position when moved (waxy flexibility), no response, loss of muscle control, and slowing down of bodily functions, such as breathing. Causes Catalepsy is a symptom of certain nervous disorders or conditions such as Parkinson's disease and epilepsy. It is also a characteristic symptom of cocaine withdrawal, as well as one of the features of catatonia. It can be caused by schizophrenia treatment with anti-psychotics, such as haloperidol, and by the anesthetic ketamine. Protein kinase A has been suggested as a mediator of cataleptic behavior. Unsuggested waxy catalepsy, sometimes accompanied by spontaneous anesthesia, is seen as an indicator of hypnotic trance. Suggested or induced rigi ...

Schizophrenia
Schizophrenia is a mental disorder characterized by continuous or relapsing episodes of psychosis. Major symptoms include hallucinations (typically hearing voices), delusions, and disorganized thinking. Other symptoms include social withdrawal, decreased emotional expression, and apathy. Symptoms typically develop gradually, begin during young adulthood, and in many cases never become resolved. There is no objective diagnostic test; diagnosis is based on observed behavior, a history that includes the person's reported experiences, and reports of others familiar with the person. To be diagnosed with schizophrenia, symptoms and functional impairment need to be present for six months (DSM-5) or one month (ICD-11). Many people with schizophrenia have other mental disorders, especially substance use disorders, depressive disorders, anxiety disorders, and obsessive–compulsive disorder. About 0.3% to 0.7% of people are diagnosed with schizophrenia during their lifetime. In 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Symptoms And Signs Of Mental Disorders
Signs and symptoms are the observed or detectable signs, and experienced symptoms of an illness, injury, or condition. A sign for example may be a higher or lower temperature than normal, raised or lowered blood pressure or an abnormality showing on a medical scan. A symptom is something out of the ordinary that is experienced by an individual such as feeling feverish, a headache or other pain or pains in the body. Signs and symptoms Signs A medical sign is an objective observable indication of a disease, injury, or abnormal physiological state that may be detected during a physical examination, examining the patient history, or diagnostic procedure. These signs are visible or otherwise detectable such as a rash or bruise. Medical signs, along with symptoms, assist in formulating diagnostic hypothesis. Examples of signs include elevated blood pressure, nail clubbing of the fingernails or toenails, staggering gait, and arcus senilis and arcus juvenilis of the eyes. Indication ...
